To all whom it may concern: A

Be it known that I, THOMAS LUND, aciti zen of the United States, residingat'BeW erly, in the county ofEssex and State of Massachusetts, have invented certain Im provements in Apparatus for and :.Methods of Treating Heels ofwhich the following description; in connection with:the ac'come panyingdrawings, is a specificatiom-like reference characters on the drawings indi: cating like parts in the several-figures. ThlS invention relates to': apparatus for and method of preparing heelsfor compres S1011. :i .-j I .3!

It has been found in practice that Ione effective way to produce heels is to build them with paste as a connector betweenthe'lifts, with orwithout nailing them,-.then to hold them under pressure until the right-con dition of the heel has been attained byethepartial setting-of the paste'and the absorp' tion'of a portion of the moisture of the paste by the lift materia'ls, and I then to subject A them to heavy compressionwhile. they are inc-the proper condition. The time required for thus conditioning heels preparatory to compression'varies with the heel stock, the kind of paste used, and the humidityand i ii temperature of the atmosphere. Satisfactory results are, however, dependent-to a= large degree upon the pressure with which the heel is held. Experiments have shown that variations in pressure within practical- Specification of Letters Patent.

pensive and space-consuming apparatus when fprovided'to hold the heels under pr'es s lufi'e or any considerable: length of time;

e fore, is that which has been in use for many years'm which the girl who buildspasted heels transfers each heel, nwet -withpaste, from the building device to a board-convenpopular system-of heel pressing, therei I ientlyglocated at herside. The board isusually large enough to hold four rows of five mens heels.- fter the board vhas beeii tilled, it istransferred to a press iin-i which lli'lS stacked bth'erfilled boards to the height or capacity? of thepress,-'*which may vary' from p20. to; 60.: boards, accordingi to the height of the heels being. made..-"iThe press-mayebe of any known orsuitabletype, such' forexample. as a screwpresshaving a stationary r foot plate and a; platen forced downwardly upon' the: stack .-of "loaded heel boards by ahand-wheel operated screw;

In aboard press-"system the heels on each board are subjected in parallel to pressure between the top face-'of thatboardeand the lower face'of the. superposed board. Itvis obvious that 1 in .such' 1 an 'eari'angement the highest three or fouriheels' oniatboard 'get the maximum pressure and if any-heels on the board arefisubstantially:lower than those highest ones, Ithe high fheels revent the boards from subjecting such'lowz' heels to pressure. The result is that one can usually reach into-a; press while the pressureis'on f limits multiply manifold the rapidity with ;1nd find some heels thatvare under'no pres- 2 form pressure, largely because of the fact that-the heel. stock, or. liftingp?v varies in thickness, as well 'as'in density. As the heels come from the builder to the press they differ substantially vLrom one another in height despite all the care it is practical to exercise. To deal with this situation apparatus has been devised to subject heels to pressure individually as for example, of the Ferriswheel type illustrated in Hudson Patent -No.=1,156,842; This is obviously an ex" sure, as evidenced by the fact that theyfcan be moved sidewise between rthe boards by the finger. These heels obviouslywill dry' with the lifts .in loose relation to .one anotherand not be properly conditioned for com-' pressing and the product will be relatively inferior heels.' a a methods of treating-heels as to" render this popular system of making heels free or relatively free from the defects or objections, an illustrative example of which has-been above pointed out.

l/Vith this object in view one featureiof,

this invention consists in a heel board "of dimensions to hold a plurality of-heels in an .105 apparatus for pressing heels and having a! cushionheel-engagingface.- Another fea-" ture of the invention consists in an apparatus for treating heels comprising a press and a plurality of superposed heel boards in which each upper board covers the heels on t -lower boardand imwhich boards have pressure faces constructed and arranged to distribute the pressureof the pressupon the high and also uponthe low heels. The pres sure surfaces may be cushions, springs, or a. facing rif'conipiess'i'ble material in'to'which the high heels can sink far-enough to permit pressure transmitting engagement with the heels that are-slightlylower, asfor example by reason of non-uniformity in the thickness of different pieces of heel lifting. -:The pressure distributing surface may be on-the heel supporting side of the boardaor on theheel covering side. :ln-anotheniof its'aspectsthi's invention comprises. that improvement :in' methods ;of: treating heels which: consists arranging .upon a board aplurality ofj'heels of ;approximately the; same height; covering then'heels and applying pressure. and trans mittingxtherpressure to 1 individual heels on the K board-1 through individually yielding transmitters capable ofitaking .up any maria-- tion thatv-occurs in: the height Qof the heels on'the board; a

The board may be of the usual heel board size and should permit at least four heels to be arranged on it, the same being shown as carrying fou'r rows of'five each of 'mens heels.

The base 20 of the board may be made of suitable timber such as pine and is preferably thick enough (about three-quarters of an inch) to be comparativelyrigid,

This result is particularly; well assuredby the use of such'cushion surfaces as the separate studs 25, fingers 42 and the knobby or. theribbedsurfaces shown in .Fig; 3.

The heels shrink more .o'rless if-theyre; main irfthe press for long and the cushion faced boards have the advantage of expjand ing to take up the space caused by such shrinkage and maintain the pressure substantially uniform while the heels are in the press.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1.
